Description
Technical field
The utility model belongs to the part field of electric door, relates to a kind of buffer bar, is specifically related to the crashproof buffer bar of a kind of electric door.
Background technology
Along with socioeconomic development and scientific and technical making rapid progress, electric door substitutes standard machinery door gradually and is widely used in the places such as star hotel, office premises, elevator.Electric door, on use & Control, has hand control and automation control system to meet the opening and closing requirement of user to industrial door; In security reliability, be provided with a function such as body Anti-blockage or infrared ray sensing at closing time.Buffer bar is the important spare part of electric door, plays the effect of buffering when electric door is closed, thus prevents the mutual collision of hard door-plate, can extend the application life of electric door.
The crashproof buffer bar structure of existing electric door as shown in Figure 1, mainly comprise plane 1 ', the cambered surface 2 ' be connected with plane 1 ' both sides one, be arranged on one side that plane 1 ' deviates from cambered surface 2 ' on and symmetrically arranged L-type buckle 4 ', described plane 1 ' and cambered surface 2 ' form accommodation space 3 ', be provided with the back-up block 5 ' connecting plane 1 ' and cambered surface 2 ' in described accommodation space 3 ', described back-up block 5 ' is perpendicular to plane 1 '.Because this buffer bar defines larger accommodation space 3 ', and only use two parallel back-up blocks 5 ' to support, cause its in use easy compressive deformation and former state can not be recovered, lose due cushioning effect.
Summary of the invention
The utility model object provides a kind of electric door crashproof buffer bar to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: the crashproof buffer bar of a kind of electric door, it comprises plane, the convex globoidal be connected with described plane both sides one, described plane and convex globoidal form accommodation space, the one side that described plane deviates from convex globoidal is provided with two L-type claws, described L-type claw is that axial line is symmetrical arranged and the reverse extension of its claw with plane centreline, two symmetrical arc support are provided with in described accommodation space, described arc support is connected with plane and convex globoidal one respectively, described in the gap ratio of described arc support, the spacing of L-type claw is little.
Optimally, described arc support is protruded towards the both sides of plane.
Further, the junction of described arc support and plane and convex globoidal is provided with the first groove.
Further, the centerline of described arc support is provided with the second groove.
Further, the plane between two described arc support is provided with waveform burr.
Further, contact holding wire is provided with between two described arc support.
Because technique scheme is used, the utility model compared with prior art has following advantages: the crashproof buffer bar of the utility model electric door, two symmetrical arc support are set in the accommodation space that plane and convex globoidal are formed on the one hand, and arc support is connected with plane, convex globoidal one; On the other hand the spacing of two arc support is arranged less, be so all conducive to improving convex globoidal and be squeezed and restorable ability.

Wherein, 1 ', plane; 2 ', cambered surface; 3 ', accommodation space; 4 ', L-type buckle; 5 ', back-up block; 1, plane; 2, convex globoidal; 3, accommodation space; 4, L-type claw; 41, claw; 5, arc support; 51, the first groove; 52, the second groove; 53, waveform burr.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described in detail:
Below about in the definition in direction, defined according to the direction observed in Fig. 2.And conveniently describe, on the left of definition plane 1 is a limit, on the right side of plane 1 while be b limit; Fig. 2 is the front view of the crashproof buffer bar of electric door, is also its end view, therefore a limit, b limit also respectively with electric door the end face of crashproof buffer bar perpendicular.
The crashproof buffer bar of electric door as shown in Figure 2, mainly comprises plane 1, convex globoidal 2, L-type claw 4 and arc support 5.
Wherein, convex globoidal 2 is connected with the both sides one of plane 1, thus forms the accommodation space 3 corresponding with its shape.And plane 1 deviate from convex globoidal 2 one side (i.e. the bottom surface of plane 1) on be provided with two L-type claws 4; These two claws 4 are with the center line of plane 1 for axial line is symmetrical arranged, and the reverse extension of its claw 41 (namely stretching out), for being fixed this crashproof buffer bar in electric door.
Arc support 5 has two, and they to be arranged in accommodation space 3 and with the center line of accommodation space 3 for axis of symmetry; And the upper end of arc support 5 is connected with convex globoidal 2 one, its lower end is connected with plane 1 one, thus surround a little accommodation space, the sensing devices such as such as contact holding wire, pressure sensor can be embedded in this little accommodation space, electric door being closed can automatically open when clamping foreign matter or human body behind the door, preventing from crushing.The convex arc of these two arc support 5 can opposingly be arranged, thus forms the structure that end face is similar to circle; Also can arrange in opposite directions, thus form the structure that end face is similar to X-shaped; But their distance can not be too far away, otherwise easily cause compressive deformation and can not recover the mood of former state, therefore the maximum spacing of two arc support 5 should control less than the spacing of two L-type claws 4.
In the present embodiment, as shown in Figure 2, the convex arc of arc support 5 protrudes towards the both sides (a limit and b limit) of plane 1, and namely opposing setting of the convex arc of two arc support 5 forms the structure that its end face is similar to circle.In order to improve the ability of arc support 5 compressive deformation, make it can produce deformation when being subject to less pressure, arc support 5 is provided with the first groove 51 with the junction of plane 1 and convex globoidal 2 on the one hand; On the other hand the centerline of arc support 5 self is provided with the second groove 52, and this second groove 52 is arranged on the face that two arc support 5 arrange in opposite directions.And being positioned at a protruding block in the plane 1 between two arc support 5, the upper surface of protruding block is waveform burr 53, can limit the degree of crashproof buffer bar deformation on the one hand, improves the ability that it resiles; Can assist fixing on the other hand or connect the sensing devices such as contact holding wire.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
